Benefits of technology

This patent is about a device that generates aerodynamic vortices on the side edge of a main wing or regulating flap to increase the lift of an aircraft during take-off and landing. The device includes a bundle of tip vortices that form a vortex coil and dissipate quickly, reducing resistance and increasing the ratio of lift to resistance. This allows for a minimum separation between aircraft and improves the control of gusts and flight dynamics. The device can be easily integrated with existing aircraft designs and requires minimal resources.

Problems solved by technology

The decomposition of the previous central tip vortex into a vortex coil reduces the life and circumferential velocity of the vortex as a result of increased dissipation.

Embodiment Construction

[0046]FIG. 1 shows an aircraft 1 with a fuselage 2 and a wing 3 as seen from the rear and in the direction of flight, or along the longitudinal axis of the aircraft. In this viewing direction the right-hand of the two wings of the aircraft is thus shown with the half span width S2. On the main wing 9 of the wing 3 as shown are represented an inner 4 and an outer 5 high-lift flap,in each case in its extended state, and also two engine nacelles 6a, 6b. The inner and the outer high-lift flap 4, 5 have in each case an inner end 4a and 5a respectively, facing towards the fuselage 2 and an outer end 4b, 5b respectively, facing away from the fuselage 2, or facing towards the wing tip. Likewise the main wing 9 has an outer end 9b, situated opposite to the fuselage-side end 9a of the main wing 9. In this context the term “end” is used for the spanwise side edge of the contour of the high-lift flap 4, 5, or of the main wing 9, respectively.

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to PCT Application No. PCT / EP2009 / 004207, file Jun. 10, 2009; which claims priority to German Patent Application No. DE 102008027618.9, filed Jun. 10, 2008, and claims the benefit to U.S. Provisional Application No. 61 / 060,210, filed Jun. 10, 2008, the entire disclosures of which applications are hereby incorporated by reference.BACKGROUND[0002]The invention concerns a device for the generation of aerodynamic vortices and also a regulating flap and wing with a device for the generation of aerodynamic vortices.[0003]Modern commercial aircraft have high-lift aids in order to generate the necessary lift at low speeds during the take-off and landing phases. From the general prior art it is of known art that aerodynamic lifting surfaces such as high-lift systems (high-lift devices) and main and auxiliary aerofoil devices are fitted with wing tips that are cut off straight, or rounded, or with so-called winglets...
